Abstract
The utility model discloses a safety mechanical handle for a punch, which is used for a protective device of a punching machine with safe operation, which comprises steel cables, an outer casing, and safety ropes. The utility model is characterized in that an amplifying device with the travel of simultaneous man-machine reverse movement is arranged; The utility model makes use of the self power and inertia of the punching machine to realize the simultaneous man-machine reverse movement. When the slider falls, the hand can be forcibly drawn from a hazardous area to realize the safe operation of the punching machine. During the material taking operation, workers can not be influenced. The utility model has the advantages of simple structure, convenient operation, no energy consumption, large travel, and high safety and can avoid the personal accident caused by the punching machine. The utility model is suitable for open type punching machines with the range from 15 to 300 tons and closed type punching machines with the range from 15 to 300 tons.
Description
The utility model relates to the lathe auxiliary device, especially relates to a kind of punching machine safety machinery handle that is used for the operating punch machine safety guard.
Along with developing rapidly of China's industry; punch press is rolling up; because most of punch presses still are in state hand-manipulated in Multi-varieties and Small-batch Production; and most of punch presses all do not have safety guard; because of the personal injury that a variety of causes causes very frequent; the report that punch press cuts off finger is reported in media again and again, has arrived stage startling, non-regulation so far.The patent " punching machine safety manipulator " (notification number CN2040409U) that the applicant applied in 88 years is though there is the advantage that can force to pull out the hazardous area, but crossbeam can influence the speed of debuging mould, influence operating efficiency, and do not have stroke amplification device, inconvenient operation.
Thereby the purpose of this utility model be to provide a kind of utilize punch press power realize man-machine synchronous backward motion reach the purpose of punching machine safety operation, simple and compact for structure, stroke can amplify, the punching machine safety machinery handle of easy to operate, drawing-type.
The purpose of this utility model is achieved in that at the utility model and comprises steel wire rope, shell and safety rope, and an end of safety rope is fixed on the suspension ring, and the other end has the collar, and feature is also to comprise man-machine synchronous backward movement travel amplifying device.
The utility model is because design has man-machine synchronous backward movement travel amplifying device, steel wire rope one end is fixed on the slide block of punch press, the other end is fixed on the suspension ring, so just can utilize the power and the inertia of punch press self to realize man-machine synchronous backward motion, when falling, forces slide block to pull out the hazardous area, so just reached the purpose of punching machine safety operation, and can not be affected during workman's feeding, can send arbitrarily and get labor and materials, side effect such as the workman does not have any feel discomfort, is in the way, fatigue.The utlity model has the personal injury that can eliminate punch press and bring, simple in structure, compact, easy to operate, easy to manufacture, stroke amplifies, cost is low, protective effect is directly perceived, safe and reliable, the advantage that improves work efficiency, no energy consumption, is applicable to that 15-300 ton open type and closed punch and ram travel are the various pressing equipments of 25-200 millimeter.
Fig. 1 is the structural representation of the utility model embodiment 1.
Fig. 2 is the structural representation of the utility model embodiment 2.
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
Embodiment:
The utility model comprises steel wire rope 3, shell 4 and safety rope 14, and an end of safety rope 14 is fixed on the suspension ring 13, and the other end has the collar 15.Man-machine synchronous backward movement travel amplifying device is by roller gear 7, fan-shaped pulley 5, cylinder pulley 11, tooth bar extension bar 2, tooth bar 6, return spring 10 and steel wire rope 3 are formed, wherein roller gear 7 and fan-shaped pulley 5 coaxial joining together, and be installed in the shell 4, the upper end of gear extension bar 2 is fixed on the slide block 1 of punch press, following termination stretches in the shell 4 and the tooth bar 6 that is meshed with roller gear 7, steel wire rope 3 one ends are fixed on the base of fan-shaped pulley 5 by steel wire rope fixation clip 8, the other end is through fan-shaped pulley 5, steel wire rope holder 16, cylinder pulley 11 is fixed on the hook of return spring 10, the other end of return spring 10 is fixed on the spring fixed seat 9, and draw runner 12 is fixed between steel wire rope holder 16 and the suspension ring 13.The maximum anglec of rotation of roller gear 7 and fan-shaped pulley 5 is 90 °.Dihedral iron 17 plays a part the utility model is fixed on the punch press.
The mother who during use the collar 15 is placed in the right hand refer to and forefinger between.When slide block 1 moves downward, slide block 1 promotes tooth bar extension bar 2 and tooth bar 6 moves downward, tooth bar 6 drives roller gear 7 and is rotated counterclockwise 90 °, roller gear 7 just drives fan-shaped pulley 5 and also is rotated counterclockwise 90 °, return spring 10 just spurs steel wire rope 3 to left movement, steel wire rope 3, steel wire rope holder 16 just drive draw runner 12, suspension ring 13 to left movement, and the safety rope 14 that is tightened up is so just forced to pull out the hazardous area also to left movement.When slide block 1 moved upward, tooth bar 6 also moved upward, and roller gear 7 and fan-shaped pulley 5 turn clockwise 90 °, and steel wire rope 3, steel wire rope holder 16, draw runner 12, suspension ring 13 move right, and safety rope 14 is loosening, and the workman just can freely send and get labor and materials.
Because the diameter of fan-shaped pulley 5 so just can make the stroke of the stroke of draw runner 12 much larger than slide block 1 greater than the diameter of roller gear 7, has also just amplified the stroke of draw runner 12.
